WOVEN-WI RE MATTRESS.

SPECIFICATION forming part of Letters PatenttNo. 239,555, dated March 29, 1881.

Application filed November 18, 1 830. (No model.)

To all whom it may concern Be it known that I, JAMES B. RYAN, of the city, county, and State of New York, have invented a new and useful Improvement in VVoven-Wire Mattresses, of which the following is a specification.

Figure l is a plan view of theimprovement, parts being broken away. Fig.2 is a side eletlg ation, partly in section, through the line as w,

The object of this invention is to furnish woven-wire mattresses so'constructed as to be less liable to stretch and sag than when con structed in the ordinary manner, and which will not be liable to have the wire fabric pulled away from the side rails while being transported or handled.

The invention consists in a combination of woven wire, spiral and coil springs, straps,

and chains, by which the mattress is made more durable and less likely to sag or break from the frame, as will be hereinafter more fully described.

Similar letters of reference indicate corresponding parts.

A are the side rails, and 13 are the end rails, which form the frame of the mattress, and which are made sufiiciently strong to withstand the strain of the wire fabric without springing. The ends of the bars .A B are secured to each other by bolts 0, and the connection is further strengthened by metallic plates D, secured to the corners'of the frame.

E is the fabric, which is formed of double wires spirally coiled and interwoven with each other. The side edges of the fabric are strengthened by having the side coils formed of triple wires and more closelycoiled. The inner parts of the upper sides of the end bars, B, of the frame are rabbeted to receive the ends of the fabric E, which ends are flattened, and are secured to the said end bars by doublepointed tacks or staples F. The ends of the fabric E are coyered by strips G, attached to the rabbeted parts of the end rails, B, and which are made of such a thickness that their upper surfaces may be flush with the surfaces of the unrabbeted parts of the said end rails.

-hooked around the said top coils.

To the lower middle parts of the side rails, A, are attached the ends of one or more crossbars, H, to which are attached the lower ends of two or more conical spiral springs, I, the.

top coils of which rest against the fabric E. The top coils of the springs I are connected by metal straps J, the ends of which are The metal straps J keep the springs I from getting out of place and support the fabric E. The cross bars or slats H support the springs I, and at the same time stifi'en and brace the frameA B, which frame is further stiffened by an inclined brace, K, attached to the said crossslats H.

To the top coils of the springs I, at the head and foot of the mattress, are attached theinner ends of spiral springs L, the outer ends of which are attached to the end rails, E, of the frame, to hold the springs I in place and give further strength and elasticity to the mattress.

To the side edges of the wire fabric E and the top coils of the side spiral springs, I, are

attached the upper ends of a number of short chains, M, the lower ends of which are 'attached to the side rails, A, of the frame, and which are designed to prevent the fabric E from being drawn away from the side rails, A, by use or handling, or during transportation,

and at the same time hold the spiral springs JAMES B. RYAN.
